Coordinates (x, y)Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y [1st Equation]:                                                                           -10x = -7x + 6[Addition Property of Equality] Add 7x on both sides:                                   -3x = 6[Division Property of Equality] Divide -3 on both sides:                                x = -2

Step 3: Solve for y

Substitute in x [2nd Equation]:                                                                         y = -10(-2)Multiply:                                                                                                             y = 20

1) Substitute y for y in the equation and set them equal to each other.

-10x=-7x+6

*Combine like terms*

2) add 7x to both sides

-3x=6

*isolate x: divide by -3*

3) x=-2
